Assume that the solar radiation incident on earth is 1330 w/m2 (at the top of the atmosphere). find the total power radiated by the sun, taking the average separation between earth and the sun to be 1.489 × 1011 m. answer in units of w.

The total power radiated by the sun is 3.71×10^26W

Explanation:

The Earth is spherical in shape

Therefore, Area = 4πr^2 = 4×3.143×(1.489×10^11)^2 = 2.79×10^23m^2

Power radiated by the Sun = solar radiation on Earth × Area = 1330W/m^2 × 2.79×10^23m^2 = 3.71×10^26W

answer; i believe that the correct answer is (d) a very small amount of mass
